In this tutorial, we will be migrating our gerrit 2.13 to a new server running gerrit 2.15
Prerequisites
To complete this tutorial, you'll need the following 2 nodes
- Database node
- New gerrit node
Environment
Old gerrit
| OS | MYSQL | MYSQL version | Gerrit version | Authentication |
| Ubuntu 14.04 | mysql-server | 5.5.57 | 2.13 | LDAP |
New gerrit
| OS | MYSQL | MYSQL version | Gerrit version | Authentication |
| Debian 9 (Stretch) | mysql-client | 5.8 | 2.15 | LDAP |
MYSQL node
| OS | MYSQL | mysql-version |
| Ubuntu 16.04 | mysql-server | 5.7.22 |
STEP 1 On old gerrit node
Stop gerrit
Login to your gerrit server with the gerrit user or the user running gerrit. Navigate to /gerrit/bin and run
sudo ./gerrit.sh stop
Backup gerrit database
Login to your old gerrit node and backup your gerrit data base. In this case the database name is reviewdb. I use mysqldump to backup the database to a file.
mysqldum -u gerrit -p database reviewdb > reviewdb_backup.sql
If prompt, enter you mysql password. This will backup your database reviewdb to a file called reviewdb_backup.sql
Copy the .sql file to the MYSQL server node
You have 2 options to accomplish this:
- Option 1 : Use scp
- Option 2 : User rsync
For this tutorial we are going to use option 1.
The syntax of the command is :
scp path_to file_to_copy remote_usernmane@remote_server:path_to_copy_the_file
To make it go faster, i create a directory on the mysql servr node called files. From the old gerrit server a copy the .sql file to the mysql server node using the command below.
sudo scp /home/gerrit/reviewbk.sql pp@db2007.dfw.ppnet:/home/pp/files
STEP 2: On the MYSQL server
I am not going to convert the installation of MYSQL server in this tutorial. I assume, you have already MYSQL server running on your node. login to mysql and create the database reviewdb and the user gerrit, grant all privileges to gerrit user.
STEP 3: On new gerrit node
Installation
Make sure that you have Ubuntu 16.04 installed on you new gerrit node.
